    Subject[PATCH 5.15 446/779] clk: qcom: gcc-msm8939: Add missing system_mm_noc_bfdcd_clk_src
    Date
    From: Bryan O'Donoghue <bryan.odonoghue@linaro.org>

    [ Upstream commit dd363e2f7196278e7a30f509a0e8a841cb763b14 ]

    The msm8939 has an additional higher operating point for the multi-media
    peripherals. The higher throughput MM componets operate off of the
    system-mm noc not the system noc.

    system_mm_noc_bfdcd_clk_src is the source clock for the higher frequency
    capable system noc mm.

    Maximum frequency for the MM SNOC is 400 MHz.
